Green is charged with killing 27-year-old policeman Ryan Bonaminio after he’d fled the scene of a hit-and-run crash in a stolen truck.

A groundskeeper allegedly saw Bonaminio chase Green into a park. The man testified in a preliminary hearing that Green struck Bonaminio with a blunt object, then shot him three times with the officer’s own semiautomatic pistol.

Investigators later found Bonaminio’s weapon during a search of Green’s home.

Prosecutors have said that they plan on seeking the death penalty. Meanwhile, Green has pleaded not guilty.

The court expects to interview about 300 prospective jurors in the next few weeks. The judge says attorneys will question people in smaller groups than usual to allow more thorough screening.
